Abstract

A screw mixer for bulk materials is proposed, having a feed hopper and a feed trough as well as a conveying screw arranged therein and extending into a discharge tube, as well as a vibration generator. In this arrangement, the discharge tube is to have at least one inlet for added materials, in particular liquids, and the conveying screw is to be designed with a core in the region of the filling trough. The region of the discharge tube adjoining the inlet is designed as a mixing region, in which the screw is formed without a core, in order to create space for the added volume. This may be followed by a compacting region, in which the screw is again provided with a core. It is also possible to provide a plurality of inlets for adding different materials, with associated mixing region and, if appropriate, compacting region.

Description

Schneckenmischer Screw mixer

Die Erfindung betrifft einen Schneckenmischer für Schüttgüter mit einem Einfülltrichter und einer Einfüllwanne mit darin angeordneter Förderschnccke, die sich bis in ein Austragsrohr erstreckt, sowie einem Schwingungserzeuger.The invention relates to a screw mixer for bulk goods with a hopper and a hopper with a screw conveyor arranged therein, which extends into a discharge pipe, as well as a vibration generator.

Aus der DT-PS 2161369 ist eine Dosierschnecke bekannt.A metering screw is known from DT-PS 2161369.

Diese Vorrichtung ist jedoch nur für das dosierte Austragen trockener Schüttgüter geeignet.However, this device is only drier for metered discharge Suitable for bulk goods.

Der Erfindung liegt die Aufgabe zugrunde, die Dosierschn@ so weiterzubilden, daß auch Flüssigkeiten, insbesondere hochviskose, eingemischt werden können.The invention is based on the task of developing the dosing screw so that that even liquids, especially highly viscous, can be mixed in.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Austragsrohr mindestens einen Eingang für Zugabematerialien aufweist und die Förderschnecke im Bereich der Einfüllwanne mit einer Seele ausgebildet ist, die geringfügig bis in das Austragsrohr vorragt.According to the invention, this object is achieved in that the discharge pipe has at least one input for additive materials and the screw conveyor in the Area of the filling tub is designed with a soul that is slightly up to in the discharge pipe protrudes.

Nach einer bevorzugten Ausfülorungsform ist der Eingang durch einen sattelförmigen Aufsatz gebildet.According to a preferred embodiment, the entrance is through a formed saddle-shaped attachment.

Das Austragsrohr kann einen sich an den Eingang anschließenden Mischbereich und dahinter einen Verdichtungsbereich aufweisen, in dcm die Fördersclonecke mit einer weiteren Seele versehen ist.The discharge pipe can have a mixing area adjoining the inlet and have a compression area behind it, with the conveyor clone corner in dcm is provided with another soul.

Hierbei haben zweckmäßig Einfüllwanne, Mischbereich und Verdichtungsbereich etwa die gleiche Länge.In this case, it is useful to have a filling pan, mixing area and compression area about the same length.

Naclo einem weiteren Vorschlag ist in der Einfüllwanne über der Förderschnecke eine Auflockerungsvorrichtung angeordnet.Another suggestion is in the feed pan above the auger arranged a loosening device.

Nach einer aioderen Ausbildungsform sind mehrere Eingänge für Zusatzmaterialien vorgeschen.According to an older form of training, there are several inputs for additional materials forward.

Ein Ausführungsbeispiel wird anhand der Zeichnung näher erläutert. Diese zeigt den erfindungsgemäßen Schneckenmischer im Längsschnitt.An exemplary embodiment is explained in more detail with reference to the drawing. This shows the screw mixer according to the invention in a longitudinal section.

Eine Förderschnecke 1 ist an ihrem hinteren Ende 2 in einem Layer 3 über eine Lagerstütze 4 mit der Grundplatte 5 verhunden. Das andere Ende der Förderschnecke befindet sich in c illvm Austragsrohr 6. Lagerseitig ist die Förderschnecke 1 in einer Einfüllwanne 7 angeordnet und weist eine Seele 8 auf, die bis in das Austragsrohr 6 hineinragt. In den oberen 1 der Einfüllwanne 7 miinclet der Einfülltrichter 9. Die Einfüllwanne 7 ist über schwingungsisolierende Stützen 10 auf der Grundplatte 5 befestigt. Unterhalb der Einfüllwanne 7 ist ein Schwingungserreger 11 und ein Antriebsmotor 12 für die Förderschnecke 1 angeordnet. In dieser Ausführungsform weist die Einfüllwanne 7 in ihrem oberen Teil eine Auflockerungsvorrichtung 13 auf, die über die Welle 14 und das Getriebe 15 ebenfalls vom Antriebsmotor 12 bewegt wird.A screw conveyor 1 is in a layer at its rear end 2 3 connected to the base plate 5 via a bearing support 4. The other end of the screw conveyor is located in c illvm discharge pipe 6. On the bearing side, the screw conveyor is 1 in a filling trough 7 and has a core 8 which extends into the discharge pipe 6 protrudes. The filling funnel 9 is located in the upper 1 of the filling tub 7. The filling tub 7 is on vibration-isolating supports 10 on the base plate 5 attached. Below the filling tray 7 is a vibration exciter 11 and a drive motor 12 for the screw conveyor 1 are arranged. In this embodiment the filling tub 7 has a loosening device 13 in its upper part, which is also moved by the drive motor 12 via the shaft 14 and the gearbox 15 will.

Vor der Einfüllwanne 7 ist ein Eingang 16 für Zusatmaterjalien am Austragsrohr 6 ausgebildet. Der Eingang 16 kann die Form eines sattelförmigen Aufsatzes 17 haben, der mit einem Eingaberohr 18 verbunden ist. Das Rohr 15 kann ein Absperr-oder Dosierventil 19 aufweisen und mit einem Trichter 20 verbunden sein. Die Seele 8 im Bereich der Einfüllwanne 7 ragt geringfügig bis in das Austragsrolor 6 hinein. Im Bereich des Eingangs 16 und im daran anschließenden Abschnitt weist die Förderschnecke 1 keine Seele auf. Dieses st der Mischbereich des Austragsrohrs 6. Im austragsseitigen Teil des Austragsrohrs 6 ist die Schnecke 1 mit einer Seele 21 versehen.In front of the filling tub 7 there is an input 16 for additional materials Discharge pipe 6 formed. The entrance 16 can be in the form of a saddle-shaped attachment 17 connected to an input tube 18. The pipe 15 can be a shut-off or Have metering valve 19 and be connected to a funnel 20. The soul 8 in the area of the filling tray 7 protrudes slightly into the discharge roller 6. In the area of the entrance 16 and in the adjoining section, the screw conveyor 1 no soul. This is the mixing area of the discharge pipe 6. In the discharge side The screw 1 is provided with a core 21 as part of the discharge pipe 6.

Dieses ist der Verdichtungsbereich. Einfüllwanne, Mischbereich und Verdichtungsbereich haben etwa die gleiche Länge, es sei denn, daß mehrere Eingänge 16 vorgesehen sind. Dann ist ein entsprechend verlängerter Mischbereich erforderlich.This is the consolidation area. Filling pan, mixing area and Consolidation areas are roughly the same length, unless there are multiple entrances 16 are provided. A correspondingly extended mixing range is then required.

Der Eingang 16 kann selbstverständlich auch anders ausgebildet sein, z.B. als Mündung eines Druckrohres, das mit einer Förderpumpe verbunden ist.The input 16 can of course also be designed differently, e.g. as the mouth of a pressure pipe that is connected to a feed pump.

Der mit der Erfindung erzielte Vorteil best@ht darin, daß der Schneckenmischer neben der Runktion des dosierten Austrags des Schüttgutes auch das Zumischen insbesondere flüssiger, einschließlich hochviskoser Zugabematerialien ermöglicht.The advantage achieved by the invention is that the screw mixer in addition to the function of the dosed discharge of the bulk material, the mixing in particular liquid, including highly viscous additive materials.

Das Schüttgut gelangt durch den Einfülltric1oter 9 in die Einfüllwanne 7, wobei es zur Verhinderung der Bildung von Materialbrücken, falls notwendig, die Auflockerungsvorrichtung 13 passiert. Die im Bereich der Einfüllwanne 7 vorhandene Seele 8 bewirkt die Förderung einer geringeren Materialmenge in dem Mischbereich, als dieser aufnehmen kann, da die Förderschnecke 1 hier keine Seele aufweist. Dadurch ist das Fördervolumen des Mischbereichs so vergrößert, daß die Zugabe von Zusatzmaterialien durch einen oder mehrere Eingänge 16 möglich ist. Das Mischergebnis wird durch Verdichtung der Mischung im Verdiclctungsbereich verbessert. Das geschieht dadurch, daß die Förderschnecke in diesem Bereich, d-.h. im austragsseitigen Teil des Austragsrohrs 6,mit einer weiteren Seele 21 versehen i st, wodurcio t' i ne Volumensverminderung bewirkt wird.The bulk material passes through the filling tric1oter 9 into the Filling tray 7, in order to prevent the formation of material bridges, if necessary, the Loosening device 13 happened. The existing in the area of the filling tray 7 Soul 8 brings about the promotion of a smaller amount of material in the mixing area, than this can accommodate, since the screw conveyor 1 has no soul here. Through this the delivery volume of the mixing area is increased so that the addition of additional materials through one or more inputs 16 is possible. The mixing result is achieved through compression the mixture in the thickening area is improved. This happens because the Conveyor screw in this area, d-.h. in the discharge-side part of the discharge pipe 6, provided with a further soul 21, i st, what t 'i ne volume reduction is effected.

Der erfindungsgemäße Schneckenmischer läßt sich für die verschiedensten Zwecke einsetzen. So kann beispielsweise zur Herstellung kunststoffgebundener Baumaterialien in Stein-oder Plattenform in die Einfüllwanne 7 eine Sandmischung aus Fraktionen vorgegebener Korngrößen, mit oder ohne Zuscillagstoffe wie Marmormehl, Kies o.dgl. eingebracht werden.The screw mixer according to the invention can be used for the most diverse Use purposes. For example, it can be used to manufacture plastic-bonded building materials in the form of stones or slabs, a sand mixture of fractions is placed in the filling trough 7 predetermined grain sizes, with or without additives such as marble powder, gravel or the like. be introduced.

Durch dcn Eingang 17 kann dann ein Bindemittel auf Kunststoffbasis eingebracht, mit der Sandmischung vermengt und durch das Austragsrohr 6 ausgebraclot und in Formen gefüllt wenden. Auf diese Weise ist das kontinuierliche Herstellen einer schnell aushä@tenden Mischung ohne Verkrusten der Sch@ecke möglich. Nach Beendigung der Arbeit kann durch c](n Eingang 16 (in Lösungsmittel zur sclcnellen und sicheren Reinigung der Vorrichtung eingegeben werden.A plastic-based binder can then pass through the inlet 17 introduced, mixed with the sand mixture and blown out through the discharge pipe 6 and turn them into molds. This is the way of continuous manufacturing a quick-hardening mixture without encrusting the puck possible. After completion the work can be done through c] (n input 16 (in solvent for quick and safe Cleaning the device can be entered.

Sollen Baumaterialien auf der Basis einer Zement- Sand- oder Zement- Kalk- Sandmischung mit Kunststoffzusatz hergestellt werden, kann in der gleichen Weise verfahren werden mit dem Unterschied, daß nach Zugabe des Kunststoffes durch einen weiteren Eingang die erforderliche Wasse@menge eingebracht wird.Should building materials based on a cement, sand or cement Lime-sand mixture made with plastic additive can be Proceed in the same way with the difference that after adding the The required amount of water is introduced into the plastic through a further inlet will.
